LUBRICATOR.

Specification of Letters Patent.

Patented Jan. 9, 191 v.

Application iled November 7, 1914. Serial N o. 870,829.

To all 'whom t may concern:

Be it known that I, PHILE'rUs W. GATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification. This invention relates to improvements in lubricators and has for its object to provide a new and improved lubricator for use in connection with an air or steam line.

The main object of my invention is `to provide a lubricator which may be readily attached to an air or similar line, and is so arranged that lubrication will only take place upon and as a result of flow of fluid through the line.

Still another object is to provide a lubricator of the character described which may be located in any desired position without interfering with the lubrication.

Still another object is to provide in a lubricator of this nature a reservoir for oil or similar lubricant in connection with means which will enable the filling or replenishing of such reservoir no matter in what position the lubricator may be located.

These and other objects will be more fully set forth in the following specification as shown in the accompanying drawings, in which,-

Figure 1 is a side elevation showing my lub'ricator applied to an air line. Fig. 2 is a vertical section through the same.

Like numerals refer to like elements throughout the drawings.

10 designates generally my lubricator comprising a casing 10a, chambered as indicated by numeral 10b to form a reservoir. Projecting into this lreservoir is a cylinder member or portion 11, internally bored'or chambered at 11a. This chamber 11a terminates at the flange 11", as clearly shown'in Fig. 2. A duct or passage 11z is provided in the flange 11b and communicates with a cross passage or duct 12 which extends therethrough. At either side of the casing 10 are provided shoulders 10d, socketed or bored to form a continuation of the passage 12. These shoulders 10d may be internally threaded or otherwise suitably constructed for insertion of and engagement withpipe ends 13, or the like, the duct 12 forming therewith a continuous air or steam line, as

,.55 will be apparent.

Located in the portion of the chamber 11a of the cylindrical portion 11 is a fibrous material 14, or. the like, the same being highly compressed to form a compact mass.A

nally threaded sleevel.` The casing 10 is internally threaded at 10", as clearly shown A in Fig. 2, and the sleeve 16 when in similar `relation is threaded into. thecylind'er chamber 112L to bear against the washer or plate 15, thereby maintaining the material 14 in Vcompressed positi0n.

To rrender the assembling of this device more easy, I slot or groove the sleeve 16, as indicated at 16a, for engagement by a screw driver or vthe like. A plug or cap 17. is

threaded into the open portion of the chamber 11a below the sleeve 16, as1 viewed in position shown in Fig.y 2. This cap 17 is centrally apertured, as indicated at 17a, being threaded kto permit insertion and engagementl of a plug V18.V The internally bored portion ofthe chamber 11a-is of larger diameter than the external diameter of the sleeve 16, as is shown in Fig. 2, and communicating with the space between such members and the interior yof the sleeve 16 is an aperture 161. In the cylinder 11 I provide apertures 11d fora purpose to be hereinafter described. Suitably apertured bosses 10g are provided in various locations in the casing 10a, and internally threaded in these bosses are the plugs 19 similar to the plug 18. It will be apparent that by means of these plugs and threaded openings the reservoir 10b may be filled with lubrlcant no matter'in what position the lubricator may chance to be. Should the same be in a position inverted with respect'to that shown in the drawings, the chambered interior of the sleeve 16 may be filled throughthe opening Anormally closed by the plug 18.

Assuming the lubricator to be inthe position shown inthe drawing, the oil or other lubricant to be placed in the reservoir 10",

the same will flow through apertures 11d` and 16", fillingthe space or chamber in the interior of the sleeve 16. VThe tightly lcompressed fibrous material 14 will normally prevent flow of such lubricant into the passage 12 through the duct 11, but during the flowof steam, air, or similar fluid through the pipes 13 and passage 12, oil will be 11o drawn in a comminuted condition through the fibrous material 14 into the passage 12, from whence itWill be carried by the Huid to the destination of the latter to effect lubrication of the pump or the like operated thereby.

By the construction described and shown it Will be apparent that I have provided a lubricator which is an improvement on that beyond the scope of the appended claims.

'I saV I claim 1. In a device of the class described, a lubricatcr comprising a casing, said casing being provided With a reservoir, a chamber and.' means to permit the flow of lubricant from said reservoir into said chamber, said lubricator being provided with a passage therethrough for communication with a fluid line and a duct therein communicating between said chamber and said passage, means to normally prevent flow of lubricant from said chamber to said passage, said n means being arranged to permit such flow v upon 1flow of fluid through said passage.

2. A lubricator comprising a casing, said casing being provided with a passage therethrough and a reservoir, the casing being further provided VWith a chamber in communication With said reservoir and with said passage, means to normally prevent flow of lubricant from said chamber to said passage, said means being arranged to permit such flow upon flow of fluid through said passage, said means comprising brous material.

3. A lubricator comprising a casing, said casing being provided with a passage therethrough and a reservoir, the casing being further provided With a chamber in communication with said reservoir and With said passage, meansto normally prevent flow of lubricant from saidchamber to said passage, said means being arranged to permit such flow upon flow of Huid through said passage, said means comprising fibrous material, and means to permit the filling of said chamber in any position thereof.

t. In a device of the class described, a casing chambered to form a reservoir, being provided with a chamber therein in communication with said reservoir, apertured shoulders carried by said casing and a passage extending through said shoulders and casing, the former being constructed and Varranged for engagement byan air line or the like.
